BARREL DRESSING AND BORING MACHINE.

SPECIFICATION forming part of Letters Patent No. 764,624, dated July 12,1904. Application filed August 3, 1903. Serial No, 168,098- (No model.)

To all whom it may concern.-

Be it known that we, FRANK PFLUGER and lCMIL Oiuus'rENsEN, citizens ofthe United This invention relates to barrel dressing and boringmachines.

The object of the invention is to provide a suitable form of supportwith means for securing a barrel thereon in different positions, suchthat it maybe successfully operated upon with suitable boring anddressing tools.

A further object of the invention is to provide in a machine of theclass specified novel and effective means for securing a barrel invarious positions upon a rotatable support, so

that it may be readily subjected "to the opera-- tion of boring anddressing tools.

A further object of the invention is to provide, in combination withsuitable barrel supporting and rotating means, a dressing-tool which maybe employed to dress quickly and effectively the heads of barrelsmounted on a support.

'ith the objects above mentioned and others in view, as will appear asthe invention is fully disclosed, the same consists in the constructionand combination of parts of a barreldressing machine hereinafterdescribed and claimed, and illustrated in the accompanying drawings, itbeing understood that various changes in the form, proportions, andexact mode of assemblage of the elements exhibited may be made withoutdeparting from the spirit of the invention.

In the drawings, Figure 1 is a view in side elevation of the supportingdevice having a barrel mounted thereon and of the boring mechanism inposition above the barrel to be brought into engagement therewith. Fig.2 is a view principally in vertical section in a plane at right anglesto that of Fig. 2, showing the operation of the devices for securing abarrel in position upon the support. Fig. 3 is a view in plan of thebarrel secured upon the support in horizontal position, the supportingdevices being indicated in dotted lines.

Fig. 1.

Fig. iis a sectional view on the line 4 i of Fig. 3. Fig. 5 is a view invertical section through the barrel and a portion of the supportingdevices with the dressing mechanism shown in operative position abovethe barrel. Fig. 6 is a view in plan to show the lateral movement of thedressing devices over the head of the barrel. Fig. 7 is a plan View ofthe supporting-disk; Fig. 8 is a view in vertical section through thesupporting-disk along one of its diameters. Fig. 9 is a plan view of oneof the slidable members to which the cords shown in Fig. 3 are attached.Fig. 10 is a side View of the members shown in Fig. 9. Fig. 11 is a sideview of one of the pivoted dogs. Fig. 12 is a face view of the dog shownin Fig. 11.

Referring to the drawings, in which corresponding parts are indicated bythe same characters of reference in the several views in which theyappear, 1 designates a vertical shaft mounted for rotation in anysuitable supporting devices. (Not shown.)

2 designates a beveled gear rigidly associated with the shaft 1 and inmesh with a beveled pinion 3, mounted on a shaft 4 at right angles tothe shaft 1 and bearing a suitable driving-pulley 5, which is preferablyassociated with clutch mechanism of any suitable form and indicateddiagramatically at 6.

Rigidly mounted upon the upper end of the shaft 1 is a disk 7, theconstruction of which is shown in detail in Figs. 7 and 8. The disk 7 isprovided at opposite sides of its center with rectangular openings 8,and at either side of each of the openings 8 is provided anupwardly-projecting stud 9, having the upper end thereof inclined, asshown, so that the studs 9, taken collectively, form a seat for thecurved surface of a barrel, as best shown in On the lower surface of thedisk 7 in suitable relation to the openings 8 in the disk are providedtwo pairs of downwardly-disposed brackets 10, which afford bearings forpivoted dogs 11 of the form shown in Figs. 11 and 12. Each of the dogs11 is provided near its lower end with a transverse opening for thepassage of a pivot-pin 12, which extends through the openings providedin the brackets 10, and at the upper end each of the dogs is providedwith a pair of laterally-extending lugs 13 of preferably circularcrosssection, which engage with grooves 14, formed for that purpose onthe under surface of sliding jaws 15 or with similar grooves uponslightlydifferent jaws, presently to be described. The dogs 11 extend upthrough the openings 8 in the disk 7 to the extent shown in Figs. 2, 4,and 5 and on their inner faces are provided with cam-surfaces forengagement with a spreader 16, which is slidably mounted upon the shaft1 and comprises a hub 17, having a circumferential groove thereon, andthe upwardly-disposed arms 18, which are adapted for engagement with thecam-faces formed on the dogs 11. The spreader 16 is actuated by means ofa pivoted foot-lever 19, mounted in a suitable bracket 20 and providedat one end with pins for engagement with the groove in the hub 17 of thespreader. The jaws 15 are slidably supported upon the disk 7 and arepreferably of the form illustrated in Fig. 5, each being recessed on itsunder surface, as shown, for engagement with the upper end of one of thedogs 11, having on its upper surfacea curved and serrated grippingface,which is inclined outwardly and upwardly, as shown at 21, to adapt itfor engagement with the inner face of the end portions of the staves ofa barrel which project beyond the head thereof, as shown in Figs. 2 and5.

The jaws 15 are positively connected with the dogs 11 by the engagementof the lugs 13 on the dogs, with the grooves 14 on the under surface ofthe jaws, so that the outward movement of the upper ends of the dogscauses a correspondingoutward movement of the two jaws, and the oppositemovement of the dogs causes a corresponding inward movement of the jaws.The inward movement of the jaws is provided for by curving inward thelower ends of the dogs, which are engaged by the curved lower portionsof the arms 18 of the spreader when drawn down out of engagement withthe cam-faces on the upper portions of the dogs. It is thus apparentthat the movement of the spreader up and down on the shaft 1 will throwthe jaws into engagement with the ends of the spokes of a barrelsupported on the disk 7 or out of engagement therewith, according as thespreader is moved up and down.

The jaws 15 are of substantially the same dimensions,and thegripping-faces thereof are at equal distances from the shaft 1, uponwhich the disk? is supported, so that when a barrel is gripped by meansof these jaws it will beheld in the position shown in Fig. 5,

- with the axis thereof above the center of the disk 7 In order tosupport the barrel eccentrically, as shown in Fig. 2, the jaws 15 willbe replaced by jaws 15 and 15, which have the gripping-faces disposed atunequal distances from the center of the disk 7, and when thrown intooperative position, as indicated in Fig. 2, support a barrel with itsaxis con siderably out of alinement with the axis of the shaft 1, theobject of this mode of support being to hold the barrel in such positionthat when the boring mechanism (shown in Fig. 2) is putin operation thebung-hole formed thereby will be near the margin of the head of thebarrel.

In order to support a barrel in the horizontal position, (illustrated inFigs. 3 and 4,) it is necessary to substitute for the jaws 15 or 15 and15", above described, the slidable members 24, each of which is recessedon its under side and provided with grooves 25 for engagement with lugs13 on the dogs 11 and is provided on each side with a grooved roller 26,which is freely rotatable upon a lateral projection from the member 24.The members 24 are also provided at their inner ends with openings 27for the passage of small wireropes 28, the purpose of which is clearlyindicated in Figs. 3 and 4.

The wire ropes are secured in position, as shown in Fig. 3, by passingtheir ends through the openings 27, provided therefor, and passing theropes under the rolls 26, so that the ends of the ropes are crossedbetween the members 24, and any outward movement of the members 24 willresult in the contraction of the loops formed by the ropes, so as todraw them into close contact with the staves of the barrel B, as shownin Figs. 3 and 4.

The boring mechanism used in connection with the barrel-supportingdevices described in a preceding paragraph consists of a bracket 30,which is supported in any suitable manner, and a vertically-slidableboring-bar 31, mounted in said bracket. The boring-bar is preferablysquare in cross-section to prevent the rotation thereof and is raisedand lowered by means of a lever 32, having one end pivoted on thebracket 30 and having a pin-andslot connection with the bar31, as shownin Fig. 2. The lever is normally held in the elevated position (shown inFig. 2) by means of a counterweight, (not shown,) which is attached tothe end of a cord 33, which passes upward over any suitable form ofsupport. (Not shown.) At the lower end of the bar 31 there is pivotallymounted an angular bracket 34, upon one arm of which is provided a chuck35 of suitable form to hold an auger 36, and upon the other arm there issecured a wrench 37 for engagement with a bung-hole bushing. The angularbracket is held in position to bring either the auger or thebushing-wrench into operation by means of a pivoted latch 38,

which engages with the sides of either arm of the bracket when inalinement with the boring-bar.

When a barrel is held in the position shown in Figs. 1 and 2, the angerwill first be brought into engagement with the head of a barrel bylowering the lever 32, and the slow rotation of the barrel, with itssupport, will cause the formation of a bung-hole in the head thereof.Then the angular bracket 35 will be shifted to bring the bushing-wrenchinto the position occupied by the auger 36 in the drawings. A bushingwill then be placed upon the wrench, and the boring-bar will again belowered to force the bushing into the bunghole. The bushings areprovided externally with screw-threads, and as the barrel is rotated bythe disk 7 and the gripping devices thereon the bushing will be securelyscrewed into the bung-hole.

When it is desired to form a bung-hole in the side of the barrel, theslidable members 24 will be substituted for the jaws 15 and 15", thebarrel will be laid in horizontal position upon the studs 9, and thewire ropes 28 will be drawn over the barrel, as shown in Figs. 3 and 4.The spreader 16 will then be raised, forcing the dogs 11 outward anddrawing the ropes 28 tightly around the barrel, so that it will be heldwith the side directly under the boring-bar.

The operation of boring the side bung-hole and inserting a bushingthereinto is exactly like that described in forming the bung-hole in theend and providing it with a bushing. Therefore a detailed descriptionthereof is regarded as unnecessary.

For dressing the end of a barrel there is employed, in connection withthe supporting device already described, a supporting-lever 40, whichhas one end rounded to form a ball 41, which is adapted for engagementwith a series of sockets 42 in a vertical column 43, arranged at oneside of and somewhat above the barrel-supporting devices. The lever 40has secured thereto intermediate of the ends a scraping-tool comprisinga shank 44 and a cutter-head 45. The shank 44 extends through a slot inthe lever 40 and is securely clamped therein by means of bolts 46,extending through the lever, as shown. The cutterhead is pivotallyconnected with the shank, so as to adapt itself to the surface of thebarrel-head, and the dressing of the barrelhead is accomplished bysimply shifting the dressing-tool laterally over the barrel-head as thebarrel is rotated upon its support. The ball-and-socket connection ofthe lever 40 with the column 43 enables the lever to be shiftedlaterally to any desired extent, and the series of sockets 42 permit theadjustment of the height of the lever to correspond to the heights ofbarrels of different sizes.

WVhen a barrel is mounted upon the disk 7 to have the head thereofdressed, the gripping-jaws 15 will be used in order to insure the propercentering of the barrel upon the support.

In the foregoing description and in the drawings illustrative thereofthe framework in which the various members of the barrel dressing andboring machine are mounted has bracket 30, supporting the boring-bar andthe column 43 in which the dressing mechanism is mounted may be attacheddirectly to the wall of a shop, and no special framework to support themneed be employed.
